RAILWAY-RAIL ANCHOR.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed March 16, 1907. Serial No. 362,717.

T 0 all whom 'it may concern:

Be it known that 1, JOHN M. Scores, a citizen of the United States,residing at Racine, in the county of Racine and State of Wisconsin, haveinvented certain new and useful Improvements in Railway-Rail Anchors, ofwhich the following is a specification, reference being had to theaccompanying drawing, forming a part thereof.

This invention relates to that class of rail anchors which have opposingjaws adapted to be clamped upon the base flanges of the rails, andbearings for abutment against the sides of cross ties, to preventcreeping or longitudinal movement of the rails upon the ties.

The main objects of the present invention are to increase the grip orhold of the jaws on the rails so as to prevent any slip or end wisemovement of the rails in the jaws and generally to improve theconstruction and increase the efliciency of devices of this kind.

It consists in certain novel features of construction and in thepeculiar arrangement and combination of parts as hereinafterparticularly described and pointed out in the claims.

In the accompanying drawing like char acters designate the same parts inthe several figures.

Figure 1 is a vertical cross section on the broken line 1 1, Fig. 2, ofa rail anchor embodying the invention as applied to the base of arail'which is shown in cross section, and to the side of a tie, aportion of which is shown inside elevation; Fig. '2 is a horizontalsection and plan view on the broken line 2 2, Fig. 1; Fig. 3 is aninside elevation of one of the jaws of the anchor; and Fig. 4 is anenlarged perspective view of one of the tapering toothed grips inverted.

The anchor comprises two separate opposing jaws a, connected by abolt 1) and formed with vertical bearings c for ment against the side ofa tie (Z. The jaws are formed on their inner sides with recesses toreceive and project over the base flanges of a railway rail 0. In thesere; cesses arc fitted and movable endwise wedgeshaped or tapering andangular or flanged grips or keys f, which are formed to engage with theedges and the upper or adjoining faces of the rail base flanges.

are formed with sharp teeth or corrugations abut- 7 The'in'ner faces ofthe flanges on the grips or keys f to bite into the edges of the railbase flanges, while the inner faces of the tapering portions or bodiesof the grips are formed with diagonal or oblique teeth or corrugationsto bite into the adjoining faces of the rail base flanges. The forwardfaces of the oblique teeth preferably slope gradually backward towardthe larger ends of the grips, as shown in Figs. 3 and 4, and form sharpangles with their rear faces which are approximately perpendicular tothe rail base, so as to permit the grips to be more readily drivenforward into tight engagement with the base' flanges of the rail and tomore effectively resist any forward movement of the rail. These teethare also inclined forwardly from their outer toward their inner ends toincrease their length and hold on the rail flanges and to avoidweakening and fracture of the grips as a result of making the groovesbetween the teeth run straight across them. This inclination orobliquity of the teeth also tends to draw the toothed flanges of thegrips inwardly against the edges of therail base flanges when the gripsare driven forward in the jaws.

To prevent the parts of the anchors from becoming separated and lost ormisplaced before they are applied'to rails the grips or keys are formedon their inner sides with beveled faces g, terminating in shoulders h,as shown in Fig. i, and the jaws are formed with ears or keepers i whichoverhang the recesses therein and are bent outwardly against the beveledfaces of the grips or keys. The shoulders h by engagement with vent theremoval of the grips endwise from the jaws. The aws being separate andadjnstably connected by bolts, may be applied to rail bases of differentwidths.

lVhile the anchor as shown is composed of two like or similar jaws eachhaving a tapering toothed grip for engagementwith a tie, a jaw of thiskind maybe connected with a jaw of some other form without the toothedgri and bearing, and thus produce an eflective anchor.

In the application of the anchorlto a rail and tie, the grips or keys fare drawn out fronrthe'jzrws'a against the shoulder or stops h next tothe smaller ends of the grips, the jaws are then set over the ba eflanges of l the rails withtheir bearings 0 against the or key and abearing.

. place upon the ra side of a tie and are connected by a bolt 6, the nutbeing turned up lightly against the adjacent jaw. The tapering grips arethen driven tightly into the jaws, causing the oblique teeth on theirinner faces to bite into the opposing faces of the rail base flanges.-

The teeth on the inner faces of the flanges of the grips are nextimbedded in the edges of the rail flanges by striking the outer faces ofthe jaws with a sledge or hammer, this operation tending to increase thebite of the oblique teeth on the upper faces of the rail flanges. Thenut on the bolt is finally tightened, and if necessary locked, to firmlyand permanently grip and hold the jaws in i base.

' By means of the taperin the anchor is adjusted to rai base flanges ofdifferent thicknesses as well as of different widths, and an extendedand firm hold of the jaws upon the edges and adjoining faces of the railflanges is thus insured.

I claim:

, l. A railway rail anchor comprising a re cessed jaw and a key ofangular section fit ting in the recess of the jaw and over a rail baseflange and having teeth on its inner faces in planes at an angle toeachv other to engage with the edge and an adjoining face of the railflange, substantially as described.

2. A railway rail anchor comprising an abutment for the side, of the tiea recessed jaw and a flanged key fitting lengthwise of the rail in therecess of the jaw and tapering and movable lengthwise thereof, the bodyof the key tapering vertically and fitting between the top of the railflan e and the overhan ing part of the jaw, wh1le the flange of the eyoverhangs and engages the edge of the rail flange, substantially asdescribed.

3. A railway rail anchor comprising'a jaw recessed to receive and extendover a rail base flange, and a tapering angular key fitgrips or keysting and movable endwise in the recess of the jaw and having teeth onits inner faces to engage wit-h the edge and an adjoining face of therail flange, substantially as described.

4. A railway rail anchor comprising a recessed jaw and a taperingflanged key fitting and movable'endwise in the recess of the jaw andhaving teeth on the inner fa f its flange for engagement with the edgeof a rail base flange and oblique teeth on its other inner face for enagement with an adjoining face of the rai flange, substantially asdescribed.

I 5. railway rail anchor comprising a recessed aw, having a keeperoverhanging the opien side of the recess therein, a wedge shape arallelwith the rail and consubstantially 6. A-railway rail anchor comprising are cessed jawhaving a keeper overhanging the open 'side of the recesstherein, a tapering key of angular section fitted and movable endwise insaid recess parallel with the rail and having a beveled innerfaceengaged by said keeper and terminating in stops which prevent theWithdrawal of the key endwise from the jaw, substantially as described.

7. A railway rail anchor comprising a pair of adjustably connected jawsadapted .to be clamped on the base flanges of the rail and having abearing for abutment against the side of a tie, and a tapering key ofangular section fitting and movable endwise in a recess of one of thejaws parallel with the rail and having teeth formed on its inner facesin planes at an angle to each other, to engage with the top face and theedge of one of the rail base flanges, substantially as described.

8. A railway rail anchor comprising a pair of jawsadjustably connectedby a bolt and adapted to be clamped on the base of a rail and having abearing for abutment against the side of a tie; and a key of angularsection fitting in a recess of one of the jaws parallel with the railand having teeth on the inner faces for engagement with the edge and anadjoining face of the rail base flange, substantially as described.

19. A railway rail anchor comprising a recessed jaw, a key fitted in thejaw and a means on the jaw and on the key whereby the key is permittedto move longitudinally of the rail, but is prevented from becomingdetached therefrom.

10. A railway rail anchor comprising a recessed jaw, a key in said jaw,a keeper on the jaw and abutments on the key whereby t e key is allowedto move longitudinally of the rail, but is held from detachment from thejaw.

11. A railway rail anchor comprising a jaw a key, fitting and movablelengthwise of the rail within the jaw and diminishing in its verticaldimension longitudinally of the rail, means for forcing said key againstthe rail flange and an abutment for the side of the tie on said jaw.

12. A railwa rail anchor comprising a jaw a key which diminishes both inits vertical and horizontal di'tnens'ions longitudinally of the rail, ajaw for forcing said key against the rail and an abutment for the sideof the tie on said jaw.
